Area Forecast Discussion National Weather Service Green Bay WI 226 PM CDT Mon Jun 19 2017 Forecast discussion for routine afternoon forecast issuance .SHORT TERM...Tonight and Tuesday Issued at 226 PM CDT Mon Jun 19 2017 The latest rap analysis and satellite/radar imagery show deep layer cyclonic flow across the western Great Lakes region. Several shortwaves within this cyclonic flow are interacting with daytime instability (sb capes > 1000 j/kg over eastern WI) to produce numerous showers and scattered thunderstorms. Highest coverage of showers and storms should occur over eastern WI for the rest of the afternoon. Not out of the question any storms could produce small hail, brief gusty winds, and even funnel cloud given high non- tornadic storm parameters. The next shortwave is located over Saskatchewan and poised to arrive early tomorrow morning. Precip trends are the main forecast concern in the short term. Tonight...Upper troughing will remain firmly in place over the region. Scattered showers will likely persist into the evening but coverage/intensity should gradually diminish with loss of heating. Still though, coverage should be highest over eastern WI this evening, where a few thunderstorms will likely persist. Once the showers have ended, should see quiet conditions for a several hour period under scattered to broken clouds. Then clouds will be on the increase late tonight as a potent shortwave over Saskatchewan moves towards the region. This shortwave will generate a chance of showers by 7am over central and north-central WI. Low temps ranging from the upper 40s north to mid 50s south. Tuesday...The shortwave will track across the region during the morning before exiting in the afternoon. The higher resolution models place the highest qpf over central and east-central WI, where the best forcing via mid-level fgen/upper divergence and also instability will reside. With capes of 200-400 j/kg, a few thunderstorms could also accompany the shortwave. As the shortwave and associated precip exits, isolated to scattered showers could persist through the end of the afternoon. Highs ranging from the mid 60s north to low 70s south. .LONG TERM...Tuesday Night Through Monday Issued at 226 PM CDT Mon Jun 19 2017 The next chance of rain and the focus of this part of the forecast will be toward Wednesday evening into Thursday. A few stray showers may linger Tuesday evening over eastern Wisconsin as a short wave trough departs the area. Otherwise a surface high pressure ridge will drift over the western Great Lakes late Tuesday into Wednesday as upper heights increase and the flow aloft goes from a northwest flow regime to a zonal flow. A brief quiet stretch of weather is the result. The the next frontal system will approach from the northern plains Wednesday afternoon or Wednesday evening, followed with a cold frontal passage toward Thursday morning. Progs have slowed down the timing of arrival starting Wednesday evening. A period of PWATS climbing to 1.75 inches along and ahead of the cold front will potentially produce up to an inch of widespread rain in the 24 hour period. The slow down of the frontal system may delay the departure of the precipitation from northwest to southeast on Thursday. Progs are consistent with dropping the cold front south of the area by noon Thursday for brief trend toward drier conditions for at least northern wisconsin. A few showers may linger over parts of central and east central Wisconsin Thursday into Thursday night closer to the cold front, or mainly south of highway 10. Will keep a dry forecast going friday as drier air continues to settle southward. Consensus of the medium range progs transition to a broad upper trough dropping into the Northern and Central Plains this weekend. A southwest flow aloft over the Great Lakes will allow a moist air mass to settle into the area with a return of more precipitation. Max temperatures will depend on amount of clouds, but appears cooler than normal this weekend. && .AVIATION...for 18Z TAF Issuance Issued at 1153 AM CDT Mon Jun 19 2017 An upper level disturbance will bring another round of showers and scattered thunderstorms through early evening, with the best thunder chances occurring at the GRB/ATW/MTW TAF sites. Showers should taper off by around sunset. Another upper disturbance will bring more rain and isolated thunderstorms to the western TAF sites early Tuesday morning, and to the eastern WI TAF sites by mid morning. Ceilings and vsbys will likely fall to mvfr within the showers. && .GRB WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM.....MPC LONG TERM......TDH AVIATION.......MPC
